LN² ready? :D |
If we could get an inscurance to cover our losts, I would try it, for now it hold dry ice well for atleast 2 hours. But it didn't really improve overclocking, so sad :( |
what vga card? temp probe squeezed anywhere? readouts? |
I have a tempmeter in my tube but that is just so watch the aceton temp not raise to much. So, no temp probe, but there is a temp monitoring trick on the NVIDIA 6600 to read core temp. It goes down to +23°C, but that's enough to compare against normal heatsinks, so in some way I can say the contact with the core was pretty good. When I loaded some 3D the core temp went up to the middle 40's and to tube felt warm. Not the base, the tube itself. So basicly, I think everything went very went, except for the overclocking itself. With the 77.77 driver (very good in 3D Mark 01 with those cards) I couldn't get high scores. OC-tools would let me go over 700MHz on the core, but when I tested it I got results comparible to stock card. So I loaded another partition with 91.47 driver, é voila, I was finally doing something. Though, the final stable clocks or just above the ones I got with cold water, nothing special. Here is the result link: http://www.hwbot.org/result.do?resultId=565214 Good enough to claim the WR, but not what I hoped for :( |

Next time, try to insulate the tube itself, that's one of the main reasons the temps sucked |
Temps got lower then -66 though, but you are right on that one PJ. I didn't really care this time, as I thought anything well under -50°C was enough to get good scores. |
Did the acetone go down to -66 or the coretemp? |
Coretemp, I wish :p The aceton temp, but I remember getting lot's of better results when benching the FX57 with dry ice. Much aceton aint good, I really had to much this time. |
